------- Comment #5 from rguenth at gcc dot gnu dot org  2006-10-16 16:06 -------
Doesn't work out.  It looks like we depend on its side-effects in some
testcases:

FAIL: gcc.dg/assign-warn-3.c  (test for warnings, line 9)
FAIL: gcc.dg/assign-warn-3.c  (test for warnings, line 13)
FAIL: gcc.dg/pr29254.c  (test for warnings, line )
FAIL: gcc.dg/pr29254.c  (test for warnings, line 21)
FAIL: gcc.dg/warn-1.c  (test for warnings, line 15)
FAIL: gcc.dg/noncompile/pr16876.c (internal compiler error)
FAIL: gcc.dg/noncompile/pr16876.c  (test for errors, line 10)
...

pr29254 is artificial - it tests for the bogus warning, otherwise the warning
should be done in the frontend.
